A and D/Left Arrow and Right Arrow to move. Space/Up Arrow to jump. The player sprite is a pixel art version of a character I made up a bit ago, called Jeff. Enjoy, and try to get to the end. The rest is explained within the game.
This was an adaptation of code from Griffpatch's "Code a Platformer Game" tutorial. Some code was made from my knowledge of scratch. Thanks to Rick Astley (you'll see why).
